BALlNG-PRESS.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed November 13, 1903. Serial No. 181,076.

fo all whom it may concern:

Be it known that I, GEORGE DANIEL HAYES, a citizen of the United States, residing at Hillsboro, in the county'of Hill and State of Texas, have invented a new and useful Baling-Press, of which the following is a specification.

This invention relates to a novel balingpress designed particularly as a further improvement of the structures shown in my Patent No. 685,838 and in my copending applications Serial Nos. 127,402 and 170,7 59.

The primary object of the invention is to secure a more effective operation of the press and at the same time eliminate the long operating-lever heretofore employed and the large springs which have been disposed above the press to elect the retraction of the lever.

A further object of the invention is-to improve the tension device at the discharge end of the press, whereby the same may be constructed at less expense and manipulated with greater facility than heretofore.

To the accomplishment of these objects and others which will more fully appear the invention resides in the construction and ar.- rangement of parts hereinafter described, illustrated in the accompanying drawings, and defined in the appended claims.

In the said drawings, Figure 1 is a longitudinal section of the press complete, the discharge end thereof being shown in elevation. Fig. 2 is a horizontal section. Fig. 3 is a detail perspective view of the tension device, and Fig. 4 is a detail view of the tension lever and cam.

Like numerals of reference designate corresponding parts in the several gures of the drawings.

The body or frame of the press is constructed of metal in a manner substantially in accordance with the construction illustrated in my application Serial No. 170,7 59, and comprises the press-box 1, from which extends four angle-iron corner-beams 2, 3, 4, and 5. Above the opening 6 is located a hopper 7, and from the front end of the press-box extends a frame extension comprising parallel longitudinallydisposed channel-beams 8 and 9, preferably having top and bottom flanges, as shown, and arranged with their open sides opposed. The frame extension is slightly narrower than the main frame of the machine and includes an end bracket 10 connecting the outer ends of the beams 8 and 9.

VV'thin the press-box is mounted a reciprocatory plunger 11, rigidly connected to the end of a channel-iron plunger-rod 12, between the side walls of which is located a seat 13, formed by bending a metal strip 14 into the desired shape and rigidly securing said strip in place.. The seat 13 is designed to receive a roller 15 mounted in the lower extremity of one member 16 of an operating-toggle 17, comprising the member 16 and another toggle member 18, as shown in Fig. 1.

The toggle members 16 and 18 are preferably of U-shaped cross-sectional contour and are pivotally connected at their proximate ends by a pin or shaft 19, which forms a toggle-joint. The member 18 is in the form of an angular lever fulcrumed on a shaft 20, extending transversely between the front end portions of a pair of frame-bars 21, disposed above the beams 8 and 9 and secured at their opposite ends to the press-box and to said beams, respectively. Upon the shafts 19 and 20 are mounted pulleys 22 and 23, a third pulley 24 being mounted on the shaft 25, journaled in suitable bearings carried by a plate 26, extending transversely between the beams 8 and 9 and preferably secured to the bottom flanges thereof, as shown in F ig. 2. These pulleys are designed to facilitate the operation of a cable 27, fixed at one end to the front edge of the plate 26 and then passed around the three pulleys, as shown in Fig. 1, and passed forward for attachment to the draft appliances. It will now appear that a pull upon the cable 27 will cause the toggle-joint to be drawn down, thus straightening out the toggle and causing the advance of the plunger, it being observed in `this connection that as the plunger advances there is a constant loss of speed and a corresponding increase of power, so that as the bale increases in density the force applied to effect its further compression will be proportionately increased. When the plunger reaches its advanced position, as shown in dotted lines in Fig. 1, the member 16 of the toggle will be forced out of the seat by contact with the front wall thereof and the plunger will be suddenly retracted by the plunger-retracting spring 28, secured at one end to the plunger and at its opposite end to the plate 26 or to any other convenient part of the frame structure.

It is obvious that the slacking of the cable will not effect the restoration of the toggle to its normal position, and I therefore provide toggle-retracting means in the form of a pair TOO IOS

IIO

j U-shaped strap 33, the ends of which extend of springs 29, secured at their front ends to the lower bifurcated extremity of the lever or member 18 and at their rear ends to a bar 30, extending between the beams 8 and 9 and rigid therewith. It will thus be evident that as soon as the cable is slacked by the backing of the draft-animals the toggle-retracting springs 29 will restore the toggle to its normal position and will effect the rengagement of the roller l5 with the seat 13. Y

rIhe bottom wall 31 of the press-box is eX- tended to the rear end of the frame and tapers rearwardly, as fully explained in connection with my previous construction, in order to permit the approach and recession of the tension-plates 32, each of which connects the rear ends of the frame-beams at one side of the press, and between which plates the bale is designed to be gripped with varying pressure. To one .of these plates 32 is secured a above and below the frame and project beyond the opposite side thereof, as shown in Fig. 3. In these projecting ends of the strap 33 a cam-shaft 34 is afforded bearings. This shaft is bent at one end to form a handle 35 and midway of'its ends is deflected to define a cam or' crank 36, arranged to bear against the adjacent tension-plate for the purpose of urging the latter toward the opposite side of the press when the shaft 34 is turned.

For the purpose of retaining the cam in its adjusted positions a toothed rack 37 is secured diagonally upon the top of the frame and designed to effect the retention of the handle which engages a tooth thereof. It will be obvious that the transverse dimensions of the rear end of the press-boX-to wit, the distance between the tension-plates 32"-will be determined by the position of the cam 36 and that any desired position of the cam may be secured by engaging the handle or lever 35 with any one of the several notches in the rack 37.

It will of course be understood that various features described in my patent and in the applications hereinbefore identified may be employed in connection with the structure illustrated herein; but since said features do not constitute a part of my present invention they have not been specifically described, and, in fact, certain of them have not been shown.

It is thought that from the foregoing the construction, operation, and many advantages of the herein described invention will be clearly comprehended; but while the illustrated embodiment thereof appears at this time to be preferable I reserve the right to make such changes, modifications, and variations as may fall fairly within the scope of the protection prayed.

What I claim is- 1. In a baling-press, the combination with a frame, a press-box, a plunger, and a plunger-rod provided with a concave seat; of an operatingtoggle, one member of which is provided with a terminal roller engaging the seat in the plunger-rod and the other member of which is pivoted to the frame of the press and has a bifurcated end extending beyond its fulcrum, apair of toggle-retracting springs mounted in the press-frame and connected to the bifurcated end of the toggle member, a pulley mounted at the connectionof the toggle with the frame, a second pulley mounted at the joint of the toggle and a third pulley mounted on the-press-frame below the toggle, and a cable secured at one end to the pressframe and passed around the several pulleys.

2. In a baling-press, the combination with a frame, a press-box, a plunger, and plungerretracting mechanism, of an operating-toggle one member of which is of angular form, a shaft carried by the frame and passed through the angular member of the toggle at the angle thereof, a toggle-retracting spring secured to the angular member of the toggle at a point below the shaft, three pulleys, one carried by the frame, another at the joint of the toggle, and the third on the shaft which supports the angular toggle member, an operating-cable passed around the several pulleys, and means for automatically disconnecting the toggle from the plunger at one limit of its stroke.

-3. In a baling-press, the combination with a frame, a press-box, a plunger, and a plunger-rod provided with a seat, of an operatingtoggle one member of which detach-ably engages the seat inthe plunger-rod and the other member of which is pivoted to the frame of the press and has an end extended beyond its fulcrum, a toggle-retracting spring mounted in the press-frame and connected to the eX- tended end of the togglemember, a pulley mounted at the connection of the toggle with the frame, a second pulley mounted at the joint of the toggle, a third pulley mounted on the press-frame below the toggle, and a cable secured at one end to the press-frame and passed around the several pulleys.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in the presence of two witnesses.

GEORGE DANIEL HAYES.
